With wildfire season in the dry summer months, it’s important for rural landowners, and also people in cities, to pay attention to the health of trees. Fires starting in trees are harder to control and can spread wildfires much farther than grassfires.

Drought in California has killed an estimated 102 million trees between 2010 and 2016, according to the U.S. Forest Service. Dead trees set up tinderbox conditions that increase the summer fire risk.
